5-Amino-5-methyl-hexahydro-cyclopenta[c]pyrrole-2-carboxylic acid dimethylamide 12f (130 mg, 0.616 mmol), (2S,4S)-1-(2-chloroacetyl)-4-fluoropyrrolidine-2-carbonitrile 13g (117.4 mg, 0.616 mmol) and potassium carbonate (85 mg, 0.616 mmol) were dissolved in the solvent mixture of 2 mL of dichloromethane and 2 mL of N,N-dimethylformamide with stirring under nitrogen atmosphere. The reaction mixture was reacted overnight at room temperature. The reaction was monitored by TLC until the disappearance of the starting materials. The mixture was concentrated under reduced pressure to remove N,N-dimethylformamide and dichloromethane. The resulting residue was purified by silica gel column chromatography to obtain 5-[2-((2S,4S)-2-cyano-4-fluoro-pyrrolidin-1-yl)-2-oxo-ethylamino]-N,N,5-trimethyl-hexahydro-cyclopenta[c]pyrrole-2(1H)-carboxamide 13h (0.13 g, yield 58%) as a colorless oil.
